What’s the difference of RCCB, RCBO and RCCB module?

Update date:2017-12-06 Source:MAXGE



The function of MAXGE's RCCB  is  testing ground fault current  when detected

Fault current  leakage current is more than the leakage when the tripping current  RCCBs will loop

Disconnect. It is important to note RCCBs does not have magnetic protection  namely  and short circuit protection

The protection of thermal protection can be done in a short way.Load  RCCBs cannot automatically circuit disconnection. In addition to other protective components.Under the condition of  RCCBs on-off capacity rating only up to 800 A.In conclusion  RCCBs only leakage protection  and rated load current on and off.

With over-current protection of residual current circuit breaker.It is the Residual Current management circuit-Breakers with Integral Overcurrent protection.


MAXGE RCBOs function:Protection of short-circuit protection,excessive protection andLeakage protection.

Residual current circuit breaker module  RCCB,the full name of this is the "Residual Current" Circuit-Breakers.


Siemens RCCB modules function is  testing ground fault current when inspectionThe failure of the current leakage current is greater than that of leakage.The small and unbound substation has issued a direct circuit of the small and small circuit Disconnect. It is a small thing that can't be lost.One of the accessories of the circuit breaker is used. Must be equipped with corresponding small circuit breakers.The ordinary disconnecting device is used for the protection function.
